[gpfsug-discuss] patched rsync question

[Buterbaugh, Kevin L]

Hi All,

We are using the patched version of rsync:

rsync  version 3.0.9  protocol version 30
Copyright (C) 1996-2011 by Andrew Tridgell, Wayne Davison, and others.
Web site: http://rsync.samba.org/

    socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
    append, ACLs, xattrs, gpfs, iconv, symtimes

to copy files from our old GPFS filesystem to our new GPFS filesystem.  Unfortunately, for one group I inadvertently left off the “-A” option when rsync’ing them, so it didn’t preserve their ACL’s.  The original files were deleted, but we were able to restore them from a backup taken on April 25th.

I looked, but cannot find any option to rsync that would only update based on ACL’s / permissions.

Out of 13,000+ files, it appears that 910 have been modified in the interim.  So what I am thinking of doing is rerunning the rsync from the restore directory to the new filesystem directory with the -A option.  I’ll test this with “—dry-run” first, of course.  I am thinking that this will update the ACL’s on all but the 910 modified files, which would then have to be dealt with on a case by case basis.

Anyone have any comments on this idea or any better ideas?  Thanks!

Kevin
